01In plain English
A browser extension adds a tool to Chrome, Edge, Firefox or Safari. It can work on whatever page you are on: rewriting text in an email, pulling SEO data for a site, or saving a source for later.
02Why it matters when you are choosing
An extension brings the tool to your work instead of making you copy things into another tab. For writing, SEO and research tools, it often decides how much you actually use them.
03What to check
Ask the vendor
Check which browsers are supported and what the extension can read on the pages you visit.
04The tools
46of 96 checked
46 of the 96 tools we checked have a browser extension. Each one is checked against the vendor's own pages. A tool missing from this list may not have been checked yet, which is not the same as a no.
